JOURNAL-BOX.

Specification of Letters Patent.

Patented June 12, 1917.

Application filed August 15, 1916. Serial No. 114,956.

To all whom it may concern:

Be it known that I, ALBERT O. BUOKIUS, Jr., a citizen of the UnitedStates, residing at Chicago, Cook county, Illinois, have invented newand useful Improvements in Journal-Boxes, of which the following is aspecification, reference being had to the ac companying drawings, inwhich Figure 1 is an elevation, partly in section, of a journal boxembodying my invention; Fig. 2 is a plan thereof, partly in section;Fig. 3 shows a detail of the securing means; Fig. 1 is an elevation,partly in section, of a modified form of my invention; Fig. 5 is a planthereof, partly in section, and Figs. (3, 7 and 8 show details of thesecuring key and securing means.

My invention relates to journal boxes, and consists in providing adetachable dustguard housing, so constructed that it may be easilyremoved and replaced. My invention also consists in the construction andcooperation of the various parts which I shall hereinafter describe andclaim.

Referring to the drawings, A indicates the journal box and B thedust-guard housing. .The rear end of the box terminates in the innerwall 2 of the dust-guard chamber which acts as a retainer for the oil,as well as a confining wall for the dust-guard. The housing B has theusual opening 3 in its wall a of considerably greater diameter than thejournal, and between the wall 4 of the housing and the wall 2 is thedust-guard 5, intended to fit snugly about the journal and being free toslide upon the journal within the housing. The wall 2 of the box and thewall 1 of the housing are spaced apart by the flanges 6 of the housing,which have a tight fit against the end of the journal box. Upon thesides of the journal box and sides of the housing are cast the lugs 7and 8 respectively, through which are cored the key passages 9, 10 and10. The passage 10 is slightly curved and the passage 9 has a projection11 therein, with which the key 12 cooperates to hold the flanges 6 ofthe housing tightly against the end of the box. The key 12 is preferablymade of spring steel. The upper lug 8 is recessed at 13 for the end ofthe key, so as to prevent its turning after it has been applied.

When the housing, with the dust-guard in position therein, is applied tothe journal box and the apertures in the lugs 7 and 8 brought intoregister, the keys 12 are then inserted in the position shown in Fig. 3.Each key 12 bears at its ends against the walls of the passages 10, 10,and inits middle portion against the projection 11, and this serves todraw the housing tightly against the end of the journal box and hold theparts in such relation. When the wear which normally occurs on the walla of the housing has rendered the housing unfit for further service, thejournal box is removed, the keys 12 withdrawn, and the housing can thenbe replaced.

Normally, a journal box has to be scrapped when the outer wall of thedust-guard chamber becomes worn to the point of unfitness, but by theuse of my invention the life of a box in this regard is greatlyincreased, since the dust-guard housing may be replaced as often asdesired, with a minimum of expense.

In Figs. 4, 5, 6, 7 and 8 I have shown a modification of my device, inwhich I have provided a journal box housing formed with inner and outerwalls 14: and 15, and between which the dust-guard may be insertedthrough a slot in the top of the housing. In this form I have shown thehousing equipped with a single lug 16 on each side, which cooperateswith complementary lugs 17 on the box, to hold the housing in position.The key 18 bears against the outer faces of the apertures in the lugs 17and against a projection 19 on the opposite face in the aperture in thelug 16.

The terms and expressions which I have employed are used as terms ofdescription and not of limitation, and I have no intention, in the useof such terms and expressions, of excluding any mechanical equivalentsof the features shown and described, or portions thereof, but recognizethat various structural modifications are possible within the scopeofthe invention claimed.

What I claim is:

1. In journal box mechanism, a removable dust-guard housing comprised ofa single piece and embracing a dust-guard, said dustguard housing beingsecured to the journal box by wedging means.

2. In journal box mechanism, a removable dust-guard housing containing adustguard, lugs on the journal box and on the housing having registeringopenings, and a key for insertion through said openings to hold theparts in operative position-.

3. In journal box mechanism, a removable dust-guard housing containing adust guard, lugs on the journal box and on the housing havingregistering openings, and a key cooperating With Wedging faces in saidopenings to Wedge the parts in operative position.

a. In journal box mechanism, a journal box, a removable dust-guardhousing, the rear end of the journal box comprising the inner end of thedust-guard chamber, and

the dust-guard housing comprising the top,

sides and rear of said chamber, and a dustguard in said chamberinsertible in said housing from the forward open side thereof, saidhousing being attached to the journal boX by Wedging means.

5. In journal boX mechanism, a removable dust-guard housing containing adustguard, the journal box and the housing having registering openings,and a spring key having bearings in the opposite sides of such openingsto hold the housing tightly against the journal box. 4
